All right, I'm all caught up. Gonna have to solidly agree with the social commentary to escapism ratio. The Rosa Parks episode, the Partition of India one with the themes of religious tolerance -- definitely too much social commentary for my taste. The witch trials one was all right.
Spoilers below, you're warned people.
They keep getting rid of the characters I find interesting. What's-his-face's Nan -- interesting lady, died. That guy whose mother told him to jump out of the tree and she'd catch him, then let him fall -- interesting fellow as well, but of course he was just a one episode character. Then Mr. Medical Integrity, the medic who ran that ambulance ship -- interesting chap, but of course dies.
And they have yet to address the question on my mind. Why was the Doctor a white male in every single regeneration before, and has only now become something different?
